Lines and diagnostic testing Flashcards
Hickman line
Indwelling right arterial catheter
Inserted through cephalic or jugular vine
Superior vena cava or right atrium
Long term admin of substances into the venous system
Swan ganz catheter
Pulmonary artery catheter
Inserted through vein into pulmonary artery.
Provides continuous measurements of pulmonary artery pressure.
Arterial line
Measure blood pressure or obtain blood samples
Central venous pressure catheter
Measuring pressures in right atrium or superior vena cava
Elevate right ventricular function, right atrial filling pressure, circulating blood volume
Arteriography
Radiograph visualized injected dye in an artery
Arthrography
Invasive, contrast medium to visualize joint structure through radiograph
CT
Cross sectional X-ray attenuation that a computer reconstructus
Dx spinal lesions and brain
Doppler ultrasound
Evaluates blood flow in major veins, arteries, and cerebrovascular system
Electrocardiograph
Recording of electoral activity of heart
Electroencephalograph
Recording of electrical activity of brain
Difference between electric potential in two electrodes
Seizure activity, metabolic disorders, cerebellar lesions
Electromyography
Recording of electrical activity of selected muscle at rest and during contraction
Peripheral nerve injuries and differentiate between various neuromuscular disorders
Fluoroscopy
Show motion in joints through x ray
Excessive radiation exposure —> not common
MRI
Magnetic field to produce image of bone and soft tissue
Myelography
Invasive test combines flouroscopy and radiography to evaluate spinal subarachnoid space.
ID. Bone displacement, disk herniation, SC compression or tumors
Venography
Radiograph that visualizes injected radiopaque dye in a vein
ID tumors or blockages in venous network
